The VC made copies of the 1911 out of C-rat cans and landing mats.
While I never saw one of the "copied" ones personally, I did see a "recovered" 1911 that had been adapted to a .38 cartridge.
The magazine was, literally, made of discarded C-rat cans.
The last I knew of it, it was residing in a SF museum somewhere.
But the whole point of the copies and re-manufacturing is to use it to take a real, working weapon from the opposition.
Something we tried to teach the French Resistance in WWII with the manufacture of the two-shot Liberator.
